Episode notes
Take A Parasympathetic Pause After Workouts
- After a workout, prioritize 10–15 minutes of parasympathetic recovery (legs up the wall, seated meal, breathwork) before intense activities.
- Scott Sherr calls this the 'parasympathetic edge' to lower cortisol, raise insulin, and improve adaptation and safety.
Methylene Blue Mimics Oxygen For Low O2 Stress
- Methylene blue can act like oxygen at the mitochondrial level and offset low-oxygen situations such as airplane cabins or altitude.
- Scott Sherr notes cabin pressure reduces inspired O2 to ~17–18%, and methylene blue helps prevent mitochondrial energy decline.
Personal Case Using High Dose For Tick Bite
- Scott Sherr describes giving his mother 150 mg methylene blue for five days after a tick bite and reports she felt amazing.
- He uses higher short courses (up to ~2 mg/kg) for acute infections alongside antibiotics when appropriate.
